In April I looked at the rankings for IT Conversations shows and listed the top ten. I decided I'd take another look some months later and see what's changed.

First there are over 80 shows that have a rating of 4 or above, compared to 60 in April. There are over 1000 shows that have some kind of ranking, compared to a little over 800 in April.

To find the top ten shows, I used the same criteria as last time, ranking only shows that had more than 20 votes. Here are the top ten shows:

1. Dr. Daniel Amen - SPECT and the Future of Mental Health (Rating: 4.64)
2. Neil Gershenfeld - Fab Lab (Rating: 4.43)
3. Steve Wozniak Part 2 - Gnomedex 4.0 (Rating: 4.42)
4. Paul Graham - Hackers and Painters (Rating: 4.42)
5. Carolyn Porco - Explorer's Club (Rating: 4.39)
6. Robert Trivers - What Do We Know? (Rating: 4.37)
7. Peter Diamandis - X Prize Foundation (Rating: 4.36)
8. Cory Doctorow - Europe's Coming Broadcast Flag (Rating: 4.31)
9. Lawrence Lessig - Clearing the Air About Open Source (Rating: 4.31)
10. Clayton Christensen - Capturing the Upside (Rating: 4.30)

Of these ten, seven were on the last list, although they moved around a bit. On this list, numbers 1, 2 and 5 are new. To be fair, there are another ten shows within striking distance.

Also, since we made the move to Gigvox, there have been far fewer ratings because of authentication problems (old cookies, etc.) I'm hoping that we're getting over that and will see an uptick in ratings over the next few weeks and months. Remember to vote for your favorite shows--it helps us know what to go after.
